Description

Technical Field

[0001] This invention relates to the field of construction monitoring device technology, specifically to a dust-free intelligent management and control device for GIS and cable joints. Background Technology

[0002] Transmission and transformation construction refers to engineering construction activities carried out in a power system to realize the transmission and distribution of electrical energy from power plants to end users. This process involves multiple stages, including but not limited to:

[0003] Line construction: This includes the construction of overhead lines and cable lines. Overhead lines are typically supported by iron towers or wooden poles, while cable lines are mostly used underground in cities or under the sea to reduce the impact on the surface environment;

[0004] Substation construction: Substations are an important component of the power grid, functioning to raise or lower voltage levels to facilitate long-distance transmission or distribution to users. Substation construction involves the installation and commissioning of electrical equipment such as transformers, circuit breakers, and disconnect switches.

[0005] Civil engineering: In order to support the normal operation of the above facilities, a series of civil engineering works are required, such as building the substation foundation structure, cable trenches, and protective pipe corridors.

[0006] Equipment installation and commissioning: This includes the installation and wiring of various electrical equipment, as well as final functional testing, to ensure that all components can operate safely and stably;

[0007] Environmental protection measures: During construction, attention should also be paid to protecting the surrounding environment, taking effective dust and noise reduction measures, and properly disposing of waste.

[0008] Safety Management: Since power transmission and transformation construction involves high-risk activities such as working at heights and operating live equipment, safety regulations must be strictly implemented to ensure the safety of personnel's lives and property.

[0009] In power transmission and transformation construction, the dust-free installation of GIS gas-insulated switchgear is a crucial process. GIS is a technology that integrates the main components of a substation, such as circuit breakers, disconnectors, grounding switches, transformers, and surge arresters, into a metal-enclosed high-voltage device. It uses SF6 gas with excellent insulation properties as the insulating medium. Due to its complex internal structure and extremely high requirements for environmental cleanliness, strict dust-free measures must be taken during the installation process. Moreover, the fabrication of cable intermediate joints and terminations are key aspects of power transmission and transformation projects that require strict control of the working environment.

[0010] In the critical operations of these power transmission and transformation constructions, it is necessary to monitor the construction environment in real time. However, the current monitoring process has a low degree of automation, and the monitoring equipment is large in size, making it inconvenient to transport and move it. This makes it difficult to move the monitoring equipment to the corresponding location for real-time monitoring. Furthermore, due to different construction parameters and environmental requirements during the construction process, it is not convenient to monitor the construction environment in a timely manner, which may lead to false alarms. To address this, we propose a GIS and cable joint dust-free intelligent management and control device. Summary of the Invention

[0011] The purpose of this invention is to provide a dust-free intelligent management and control device for GIS and cable joints to solve the problems that need to be addressed in the background art.

[0012] To achieve the above objectives, the present invention provides the following technical solution: a dust-free intelligent management and control device for GIS and cable joints, comprising an integrated housing, and further comprising:

[0013] Optical zoom camera: A spherical gimbal is provided on the top of the integrated housing. The spherical gimbal is used to drive the position change of the optical zoom camera. The optical zoom camera is used to monitor the entire construction process.

[0014] Air collection port: The air collection port is located on one side of the integrated housing, and a collection tube is inserted into the air collection port. The collection tube is used to collect the gas in the construction environment.

[0015] Environmental monitoring module: The environmental monitoring module is installed inside the integrated housing. The environmental monitoring module analyzes the construction environment gas samples collected by the air acquisition port and converts the analyzed gas samples into data.

[0016] Processing chip: The processing chip is disposed inside the integrated housing. The environmental monitoring module is electrically connected to the processing chip. The processing chip is used to analyze and compare the data converted by the environmental monitoring module.

[0017] Indoor gas detection and mixing mechanism: The indoor gas detection and mixing mechanism is set at the front end of the air collection port. The indoor gas detection and mixing mechanism is used to quantitatively blow gas to the construction site. The quantitative gas is blown multiple times. After the quantitative gas blowing is completed, the gas sample of the construction environment to be tested is extracted and sent to the air collection port in a quantitative manner.

[0018] In power transmission and transformation construction, the dust-free installation of GIS gas-insulated switchgear is a crucial process. GIS is a technology that integrates the main components of a substation, such as circuit breakers, disconnectors, grounding switches, transformers, and surge arresters, into a single metal-enclosed high-voltage device. It uses SF6 gas, which has excellent insulation properties, as the insulating medium. Due to its complex internal structure and extremely high requirements for environmental cleanliness, strict dust-free measures must be taken during installation. Furthermore, key quality control aspects of power transmission and transformation projects, such as the fabrication of cable joints and terminations, and critical procedures with strict environmental requirements, all require real-time monitoring of the construction environment. However, current monitoring processes have low automation levels, and the monitoring equipment is bulky, making it inconvenient to transport and move it to the appropriate location for real-time monitoring. Moreover, due to varying construction parameters and environmental requirements during construction, timely monitoring of the construction environment is difficult, potentially leading to false alarms. This invention integrates an optical zoom camera, an air acquisition port, an environmental monitoring module, a temperature and humidity sensor, and a processing chip into a single integrated circuit. The integrated design of the casing allows for a highly integrated monitoring process, saving significant pre-construction setup work. The optical zoom camera, driven by a processing chip and a spherical pan-tilt unit, ensures real-time monitoring of the construction process during inspections. The air collection port collects gases from the construction site and transmits them to the environmental monitoring module and temperature and humidity sensors for real-time monitoring. The processing chip then compares the gas data, ensuring continuous real-time monitoring of gases generated during construction. Automatic alarms are triggered when gas anomalies occur in the construction environment, and abnormal data can be pushed to promptly terminate the construction process. During power transmission and transformation construction, the optical zoom camera provides video monitoring and recording functions, forming comprehensive digital data along with the collected environmental parameters. The indoor gas detection mixing mechanism first quantitatively blows gas to the construction site, repeatedly agitating and mixing the gases before quantitatively extracting samples. This proactive approach breaks up localized static air layers, ensuring thorough mixing of gases before sampling, significantly improving the spatial representativeness and temporal consistency of the samples.

[0019] As a further description of the above technical solution:

[0020] The indoor gas detection and mixing mechanism includes a three-way valve. The first outlet of the three-way valve is fixedly connected to a metering valve for controlling the quantitative gas blowing volume and the gas extraction volume of the construction site. The end of the metering valve away from the three-way valve is fixedly connected to a horn-shaped diffuser. The second outlet of the three-way valve is connected to an air collection port. The air inlet of the three-way valve is fixedly connected to a bidirectional air pump.

[0021] As a further description of the above technical solution:

[0022] The amount of gas quantitatively purged is the same as the amount of gas extracted from the construction site, and the volume of the gas quantitatively purged is 10L.

[0023] As a further description of the above technical solution:

[0024] The environmental monitoring module is used to detect the cleanliness, oxygen content, and sulfur hexafluoride content in the construction environment. The environmental monitoring module has three sets of detection channels, each carrying an oxygen sensor, a sulfur hexafluoride sensor, and a dust particle sensor. The air collection port is equipped with three sets of air inlet ports. Two of the three sets of air inlet ports are equipped with vacuum pumps to transmit gas to the sulfur hexafluoride sensor channel and the dust particle sensor channel.

[0025] As a further description of the above technical solution:

[0026] It also includes an audible and visual alarm, which is located on the top of the integrated housing. The audible and visual alarm is electrically connected to the processing chip. When the controller processing chip detects that the content of harmful substances in the gas sample exceeds the threshold, it triggers the audible and visual alarm to issue an alarm and simultaneously uses the processing chip to transmit the abnormal data to the background.

[0027] As a further description of the above technical solution:

[0028] The oxygen sensor is equipped with a breathable membrane at its front end. Oxygen in the gas sample of the construction environment to be detected diffuses into the oxygen sensor through the breathable membrane. The oxygen in the gas sample of the construction environment undergoes a reduction reaction on the surface of the working electrode of the oxygen sensor. The oxygen gains electrons and combines with hydrogen ions in the electrolyte to generate water. At the same time, it releases electrons. The electrons flow from the working electrode to the counter electrode through the external circuit to form a detection current.

[0029] The sulfur hexafluoride sensor includes a light source emitting unit and an infrared detector. The light source emitting unit is configured as an infrared light source and installed at one end of the sulfur hexafluoride sensor channel. The infrared light source emits light of a specific wavelength absorbed by sulfur hexafluoride molecules into the sulfur hexafluoride sensor channel. When a gas containing sulfur hexafluoride enters the detection chamber, the sulfur hexafluoride molecules absorb the infrared light energy of the corresponding characteristic wavelength. The infrared detector is located at the other end of the sulfur hexafluoride sensor channel. The infrared detector is used to receive the infrared light after the sulfur hexafluoride gas in the detection gas absorbs the wavelength light and converts the infrared light signal into an electrical signal. The infrared detector calculates the concentration of sulfur hexafluoride gas by comparing the intensity difference between the incident light emitted by the infrared light source and the infrared light detected by the infrared light source, based on the fact that absorbance is proportional to gas concentration.

[0030] The dust particle sensor includes a laser emitting unit, a scattered light collecting unit, a photoelectric conversion unit, and a signal processing unit. The laser emitting unit uses a semiconductor laser. The scattered light collecting unit is used to collect the scattered light from dust particles. The photoelectric conversion unit converts the scattered light collected by the scattered light collecting unit into an electrical signal. The signal processing unit is used to process and analyze the electrical signal, converting the electrical signal into data on the number concentration and particle size distribution of dust particles.

[0031] As a further description of the above technical solution:

[0032] It also includes a gas detection and mixing mechanism, which is located between the front end of the air acquisition port and the rear end of the indoor gas detection and mixing mechanism. The gas detection and mixing mechanism is used to uniformly mix the construction environment gas sample and deliver it to the environmental monitoring module for detection.

[0033] As a further description of the above technical solution:

[0034] The gas detection and mixing mechanism includes a mounting frame, a first elastic connecting tube, a second elastic connecting tube, a drive mechanism, and connecting tubes. The second elastic connecting tube is fixedly connected to one side of the mounting frame, and the first elastic connecting tube is fixedly connected to the opposite sides of the two sets of second elastic connecting tubes through the drive mechanism. The drive mechanism is used to mix the gas inside the first elastic connecting tube and the second elastic connecting tube. Connecting tubes extending into the second elastic connecting tube are provided through both sides of the mounting frame, and a one-way valve is provided on the connecting tube away from the air collection port.

[0035] As a further description of the above technical solution:

[0036] The driving mechanism includes a connecting plate, a first connecting seat, a through slot, a second connecting seat, and a driving cylinder. The two ends of the connecting plate are fixedly connected to the first elastic connecting tube and the second elastic connecting tube, respectively. Multiple through slots are provided on the connecting plate. The first connecting seat is fixedly connected to the top of the connecting plate. The second connecting seat is fixedly installed on the top of the mounting bracket. The driving cylinder is fixedly installed on one side of the second connecting seat. The output end of the driving cylinder is fixedly connected to the first connecting seat.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. This invention adopts a multi-module integrated design, which makes the entire monitoring process highly integrated. Moreover, such integrated setup is relatively lightweight, easy to arrange, and flexible in displacement. Compared with the traditional monitoring process, it can save a lot of pre-construction setup work. Furthermore, the optical zoom camera can be driven by the processing chip and the spherical gimbal, thereby ensuring real-time monitoring of the construction process during construction inspection.

[0039] 2. Moreover, the air collection port can collect the gas in the construction site in a timely manner and send it to the environmental monitoring module and temperature and humidity sensor for real-time gas monitoring. Then, the processing chip can be used to compare the gas data to ensure that the gas generated during the construction process is always monitored in real time. When the gas in the construction environment is abnormal, an automatic alarm can be triggered and the abnormal data can be pushed. The construction process can be terminated in time, ensuring the personal safety of construction personnel and providing a relatively safe working environment for installation, thereby effectively improving the installation quality.

[0040] 3. Furthermore, during power transmission and transformation construction, the optical zoom camera has video monitoring and recording functions, which can form full-element digital data together with the collected environmental parameters. It can be transferred to the operating unit synchronously with the entire device, and can further clarify the responsibility interface for equipment problems.

[0041] 4. Moreover, monitoring standards can be set up in real time based on key quality aspects of power transmission and transformation projects, such as GIS dust-free installation, cable intermediate joints and terminal head fabrication, and the requirements of the working environment. This enables real-time video monitoring and real-time detection based on gas monitoring standards, thus standardizing the working environment and meeting actual construction needs.

[0042] 5. The indoor gas detection mixing mechanism first quantitatively blows gas to the construction site, which can disturb and mix the gas in the construction site multiple times before quantitatively extracting samples. This setting can actively break the local static air layer, so that the gas in the construction site is fully mixed before sampling, thereby significantly improving the spatial representativeness and temporal consistency of the samples. The gas mixing structure is set in front of the air collection port to further mix the introduced gas samples from the construction site. This setting can ensure that the gas can be detected evenly and prevent the gas content at one location from being too high during the gas sample delivery to the construction environment, which would cause inaccurate detection.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1:

[0051] Please see Figures 1-5 The present invention provides a technical solution: a dust-free intelligent management and control device for GIS and cable joints, including an integrated housing 1, and further comprising:

[0052] Optical zoom camera 3: A spherical gimbal 2 is provided on the top of the integrated housing 1. The spherical gimbal 2 is used to drive the position change of the optical zoom camera 3. The optical zoom camera 3 is used to monitor the entire construction process.

[0053] Air collection port 5: The air collection port 5 is located on one side of the integrated housing 1. A collection tube is inserted into the air collection port 5. The collection tube is used to collect the gas in the construction environment.

[0054] Environmental monitoring module 6: The environmental monitoring module 6 is installed inside the integrated housing 1. The environmental monitoring module 6 analyzes the construction environment gas samples collected by the air collection port 5 and performs data conversion on the analyzed gas samples.

[0055] Temperature and humidity sensor 12: The temperature and humidity sensor 12 is disposed inside the integrated housing 1, and the temperature and humidity sensor 12 is used to monitor the temperature and humidity of the construction environment;

[0056] Processing chip 4: The processing chip 4 is disposed inside the integrated housing 1. The environmental monitoring module 6 is electrically connected to the processing chip 4. The processing chip 4 is used to analyze and compare the data converted by the environmental monitoring module 6.

[0057] Indoor gas detection and mixing mechanism: The indoor gas detection and mixing mechanism is set at the front end of the air collection port 5. The indoor gas detection and mixing mechanism is used to quantitatively blow gas to the construction site. The quantitative gas is blown multiple times. After the quantitative gas blowing is completed, the gas sample of the construction environment to be tested is extracted and sent to the air collection port 5 in a quantitative manner.

[0058] The optical zoom camera 3, air acquisition port 5, environmental monitoring module 6, temperature and humidity sensor 12, and processing chip 4 are integrated and mounted on the integrated housing 1, making the entire monitoring process highly integrated. This saves a lot of pre-construction setup work. The optical zoom camera 3 can be driven by the processing chip 4 and the spherical pan-tilt unit 2, ensuring real-time monitoring of the construction process during inspections. The air acquisition port 5 can collect gases from the construction site and transmit them to the environmental monitoring module 6 and temperature and humidity sensor 12 for real-time gas monitoring. The processing chip 4 can then compare the gas data to ensure accurate monitoring. The gases generated during the construction process are monitored in real time. When gas anomalies occur in the construction environment, an automatic alarm can be triggered, and abnormal data can be pushed to the system, allowing for timely termination of the construction process. During power transmission and transformation construction, the optical zoom camera 3 has video monitoring and recording functions, which can be combined with the collected environmental parameters to form a complete set of digital data. The indoor gas detection and mixing mechanism is designed to first quantitatively blow gas to the construction site, which can disturb and mix the gas in the construction site multiple times before quantitatively extracting samples. This design can actively break the local static air layer, so that the gas in the construction site is fully mixed before sampling, thereby significantly improving the spatial representativeness and temporal consistency of the samples.

[0059] Example 2:

[0060] The indoor gas detection and mixing mechanism includes a three-way valve. The first outlet of the three-way valve is fixedly connected to a metering valve for controlling the quantitative gas blowing volume and the gas extraction volume of the construction site. The end of the metering valve away from the three-way valve is fixedly connected to a horn-shaped diffuser. The second outlet of the three-way valve is connected to an air collection port. The air inlet of the three-way valve is fixedly connected to a bidirectional air pump.

[0061] The process involves using a bidirectional air pump to blow gas through a three-way valve, a metering valve, and a horn-shaped diffuser to disturb the construction environment. The bidirectional air pump then extracts an equal amount of the mixed gas for testing. This sequential blowing and extraction process is repeated until the pollutant concentration decreases. If the sulfur hexafluoride concentration does not decrease significantly after blowing, it indicates a continuous leak. If the dust concentration repeatedly increases, it indicates poor sealing or contamination brought in by personnel. This blowing and extraction method can also bring out and mix gas from dead corners of the construction site, making the collected samples more uniform and spatially representative. Furthermore, repeated blowing and extraction measurements generate a continuous concentration change curve, rather than just an isolated value, allowing for a clearer and more accurate determination of whether the pollutant is released instantaneously or leaks continuously.

[0062] The amount of gas quantitatively purged is the same as the amount of gas extracted from the construction site, and the volume of the gas quantitatively purged is 10L.

[0063] The amount of gas purged is the same as the amount of gas extracted from the construction site. This setting ensures that each operation involves a closed-loop, equal-volume gas replacement of the construction area, avoiding local negative pressure and the intake of air from non-target areas. It guarantees that each sample is a representative in-situ gas that has been sufficiently disturbed, improving sampling accuracy and avoiding measurement deviations caused by environmental disturbances.

[0064] Example 3:

[0065] Please see Figure 1 and Figure 2 It also includes an audible and visual alarm 11, which is located on the top of the integrated housing 1. The audible and visual alarm 11 is electrically connected to the processing chip 4. When the controller processing chip 4 detects that the content of harmful substances in the gas sample exceeds the threshold, it triggers the audible and visual alarm 11 to issue an alarm and simultaneously uses the processing chip 4 to transmit the abnormal data to the background.

[0066] When the processing chip 4 detects dangerous situations such as low oxygen content, high sulfur hexafluoride concentration, or excessive dust particles, the audible and visual alarm 11 will emit a high-decibel alarm sound. This sound can quickly penetrate the ambient noise in a noisy construction site and attract the attention of all staff on site immediately without relying on backend notification. At the same time, the audible and visual alarm 11 will flash high-intensity warning lights. This visual signal can still effectively transmit danger information when there is insufficient light, obstacles, or when personnel have their backs to the equipment. It is especially suitable for scenarios that require long-distance or rapid alarm identification.

[0067] Please see Figure 1 and Figure 2The environmental monitoring module 6 is used to detect the cleanliness, oxygen content, and sulfur hexafluoride content in the construction environment. The environmental monitoring module 6 has three sets of detection channels, each carrying an oxygen sensor, a sulfur hexafluoride sensor, and a dust particle sensor. The air collection port 5 is equipped with three sets of air inlet ports. Two of the three sets of air inlet ports are equipped with vacuum pumps to transmit gas to the sulfur hexafluoride sensor channel and the dust particle sensor channel. The oxygen sensor has a breathable membrane at its front end. Oxygen in the gas sample of the construction environment to be detected diffuses into the oxygen sensor through the breathable membrane. The oxygen in the gas sample of the construction environment undergoes a reduction reaction on the surface of the working electrode of the oxygen sensor. Taking a common acidic electrolyte as an example, the reaction formula is: O2 + 4H⁺ + 4e⁻ → 2H2O. In this process, oxygen gains electrons and combines with hydrogen ions in the electrolyte to form water, while releasing electrons. The electrons flow from the working electrode to the counter electrode through the external circuit to form a detection current.

[0068] The sulfur hexafluoride (SF6) sensor includes a light source emitting unit and an infrared detector. The light source emitting unit is configured as an infrared light source and installed at one end of the SF6 sensor channel. The infrared light source emits light of a specific wavelength absorbed by SF6 molecules into the SF6 sensor channel. When a gas containing SF6 enters the detection chamber, the SF6 molecules absorb the infrared light energy corresponding to the characteristic wavelength. The higher the concentration of SF6, the more infrared light energy is absorbed. The infrared detector is located at the other end of the SF6 sensor channel. The infrared detector is used to receive the infrared light after the SF6 gas in the detection gas absorbs the wavelength light and converts the infrared light signal into an electrical signal. The infrared detector calculates the concentration of SF6 gas by comparing the intensity difference between the incident light emitted by the infrared light source and the infrared light detected by the infrared light source, based on the fact that absorbance is proportional to gas concentration.

[0069] The dust particle sensor includes a laser emitting unit, a scattered light collecting unit, a photoelectric conversion unit, and a signal processing unit. The laser emitting unit uses a semiconductor laser. The scattered light collecting unit is used to collect the scattered light from dust particles. Dust particles of different sizes will scatter the laser at different angles, and the intensity of the scattered light is related to the size and number of particles. The photoelectric conversion unit converts the scattered light collected by the scattered light collecting unit into an electrical signal. The signal processing unit is used to process and analyze the electrical signal, converting the electrical signal into data on the number concentration and particle size distribution of dust particles.

[0070] Example 4:

[0071] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The gas detection and mixing mechanism includes a mounting frame 14, a first elastic connecting tube 15, a second elastic connecting tube 16, a drive mechanism 17, and a connecting tube 18. The second elastic connecting tube 16 is fixedly connected to one side of the mounting frame 14. The opposite sides of the two sets of second elastic connecting tubes 16 are fixedly connected to the first elastic connecting tubes 15 through the drive mechanism 17. The drive mechanism 17 is used to mix the gas inside the first elastic connecting tube 15 and the second elastic connecting tube 16. Connecting tubes 18 extending into the second elastic connecting tube 16 are provided through both sides of the mounting frame 14. A one-way valve 19 is provided on the connecting tube 18 away from the air collection port 5.

[0072] The construction environment gas sample to be tested is initially mixed by the indoor gas detection and mixing mechanism, and then enters the first elastic connecting pipe 15 and the second elastic connecting pipe 16 through the connecting pipe 18 on one side. The one-way valve 19 can prevent the construction environment gas sample from flowing back. The driving mechanism 17 then mixes the construction environment gas sample to be tested in the first elastic connecting pipe 15 and the second elastic connecting pipe 16, and then it can enter the air collection port 5 for detection.

[0073] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The driving mechanism 17 includes a connecting plate 20, a first connecting seat 21, a through groove 22, a second connecting seat 23, and a driving cylinder 24. The two ends of the connecting plate 20 are fixedly connected to the first elastic connecting tube 15 and the second elastic connecting tube 16, respectively. Multiple through grooves 22 are provided on the connecting plate 20. The first connecting seat 21 is fixedly connected to the top of the connecting plate 20. The second connecting seat 23 is fixedly installed on the top of the mounting bracket 14. The driving cylinder 24 is fixedly installed on one side of the second connecting seat 23. The output end of the driving cylinder 24 is fixedly connected to the first connecting seat 21.

[0074] In this process, after the gas sample from the construction environment to be tested enters the second elastic connecting tube 16, the drive cylinder 24 near the air inlet moves the first connecting seat 21 and the connecting plate 20 toward the air inlet. This compresses the gas sample and causes it to be rapidly ejected through the through groove 22 to the other side of the connecting plate 20. This allows the gas sample to be rapidly mixed between the first elastic connecting tube 15 and the second elastic connecting tube 16. Then, the drive cylinder 24 on the other side operates, causing the connecting plate 20 to move toward another set of connecting plates 20. At this point, the gas, after being mixed, is rapidly ejected again through the through groove 22 on the other set of connecting plates 20 to complete a second mixing. The gas then enters the air collection port 5 through the connecting tube 18 for testing. This process ensures that the gas sample from the construction environment to be tested is fully mixed, avoiding extreme test results.

[0075] Example 5:

[0076] Please see Figure 1 and Figure 2 It also includes an intercom camera 9 and an intercom speaker 10, which are installed on one side of the integrated housing 1 and are used for audio-visual communication with back-end operators.

[0077] The included intercom camera 9 and intercom speaker 10 enable real-time dialogue between on-site operators and back-end personnel, facilitating real-time monitoring of the corresponding locations and enabling real-time communication between the on-site and back-end systems.

[0078] Please see Figure 1 and Figure 2 It also includes a local video preview module 8, which is disposed on the surface of the integrated housing 1 and electrically connected to the processing chip 4. The local video preview module 8 is used to display the entire monitoring and construction process collected by the optical zoom camera 3 in real time.

[0079] Among them, the local video preview module 8 allows on-site construction personnel or managers to view the images captured by the optical zoom camera 3 directly on the device itself in real time without relying on the remote backend. This allows staff to immediately confirm whether the optical zoom camera 3 is aimed at the key construction area and whether the monitoring angle is appropriate, thereby quickly adjusting the device position or the direction of the spherical pan-tilt unit 2 to ensure that key processes are effectively covered, greatly improving the efficiency and autonomy of on-site operations.

[0080] When on-site personnel need to communicate with the back-end, they can observe the local video preview module 8 while describing the specific situation in the picture, making the communication more intuitive and accurate. At the same time, the on-site manager can also preview the picture in the local video preview module 8 and make real-time judgments and decisions on the construction process. For example, if potential risks or non-standard operations are found, they can intervene immediately.

[0081] The local video preview module 8 can serve as a reliable backup for the remote monitoring system. Even when the network signal is unstable, interrupted, or the backend system malfunctions, the local video preview module 8 can still work normally, preventing the loss of critical video monitoring information.

[0082] Please see Figure 1 and Figure 2 It also includes a power supply battery 7 and a power converter, which are disposed inside the integrated housing 1. One side of the integrated housing 1 is provided with a power supply interface that is electrically connected to an external DC power supply. The power converter is used to convert the power supply mode of the spherical pan-tilt unit 2, optical zoom camera 3, processing chip 4, environmental monitoring module 6, power supply battery 7, local video preview module 8, intercom camera 9, intercom speaker 10, sound and light alarm 11 and temperature and humidity sensor 12 to DC power supply or power supply battery 7.

[0083] The built-in power supply battery 7 eliminates the need for the entire device to be connected to an external power source at all times, which enables the device to be used in field power transmission and transformation construction sites.

[0084] The power converter can switch between an external DC power supply and an internal power supply battery 7. When the device is connected to an external power supply, it charges the power supply battery 7 at the same time.
